Question 1

The term just noticeable difference is synonymous with ______.&#10;A)separation threshold&#10;B)range threshold&#10;C)difference threshold&#10;D)absolute threshold

Accepted Answer

The just noticeable difference is the smallest detectable difference between two stimuli. It is also known as the difference threshold. This is the amount of change required for a person to notice that a change has occurred. The other options are not synonyms for the just noticeable difference. The absolute threshold is the minimum amount of stimulation needed to detect a stimulus, while the separation threshold and range threshold are not commonly used terms in perceptual psychology.

Question 2

Conduction hearing impairment refers to hearing problems that originate in the ____________.&#10;A)outer ear&#10;B)inner ear&#10;C)outer and middle ear&#10;D)auditory pathways and brain

Accepted Answer

Conduction hearing impairment refers to hearing problems that originate in the outer or middle ear, such as blockages or damage to the ear canal or eardrum, or problems with the middle ear bones. It does not involve issues with the inner ear, auditory pathways, or brain.

Question 3

Which of the following properties of sound is the most similar to the brightness of light?&#10;A)pitch&#10;B)volume&#10;C)purity&#10;D)timbre

Accepted Answer

Volume in sound is analogous to brightness in light because both describe the intensity or power of the phenomenon. Brightness refers to how much light is emitted or reflected, making objects appear more luminous or less so, while volume measures the loudness of sound, determining how intense or soft it is perceived.

Question 4

The tendency to interpret an object as always being the same physical dimensions,regardless of its distance from the viewer,is known as _____________.&#10;A)size constancy&#10;B)shape constancy&#10;C)brightness constancy&#10;D)color constancy

Accepted Answer

Size constancy refers to our ability to perceive the size of an object as being constant, even when viewed from different distances. This is why we still perceive a person as being a certain size even when they are far away from us, and why we don't perceive objects as getting smaller as they move further away. The other options (shape constancy, brightness constancy, and color constancy) refer to different aspects of perception, but not to the specific phenomenon described in the question.

Question 5

Receptor cells in the retina responsible for color vision and fine acuity are ______.&#10;A)bipolar cells&#10;B)ganglion cells&#10;C)rods&#10;D)cones

Accepted Answer

Cones are responsible for color vision and fine acuity, while rods are responsible for low light vision. Bipolar and ganglion cells are involved in transmitting signals from the photoreceptor cells to the optic nerve, but are not directly responsible for color vision or fine acuity.

Question 6

An illusion ________________.&#10;A)is the same thing as a vision&#10;B)is due to the action of the rods versus the cones in the retina&#10;C)is a perception that does not correspond to reality&#10;D)corresponds directly to something that you dreamed

Accepted Answer

An illusion is a perception that does not correspond to reality. It can be due to various factors such as sensory deception, misinterpretation of stimuli, or distorted cognition. It is not the same as a vision, which refers to a clear mental image of something that exists or has existed. The rods and cones in the retina can contribute to illusions, but their action alone does not create them. Illusions do not necessarily correspond directly to something that you dreamed, although dreams can involve illusions.

Question 7

In the process known as_____________,sensory receptors become less sensitive to repeated presentations of the same stimulus.&#10;A)sensation&#10;B)sensory fatigue&#10;C)adaptation&#10;D)discrimination

Accepted Answer

Sensory adaptation is a process in which sensory receptors become less responsive to a repeated stimulus. This allows the brain to focus on detecting changes in the environment rather than being overwhelmed by constant sensory information. Sensation refers to the process of detecting stimuli and transmitting that information to the brain. Sensory fatigue occurs when a sensory receptor is exposed to a continuous stimulus for a prolonged period of time, leading to a decrease in responsiveness. Discrimination refers to the ability to differentiate between different stimuli.

Question 8

The reason that there are three semicircular canals is so that ______________.&#10;A)we have one canal to sense motion in each of the three planes&#10;B)we can see the world in three dimensions&#10;C)we can detect sound locations in the three-dimensional world&#10;D)we have an extra if one is broken

Accepted Answer

The three semicircular canals are positioned perpendicular to each other and are each responsible for detecting motion in a different plane. This allows us to have a sense of spatial orientation and balance in three dimensions.

Question 9

Texture gradient refers to the fact that texture appears to become ______.&#10;A)more detailed in the distance&#10;B)more detailed as brightness increases&#10;C)less detailed in the distance&#10;D)less detailed when it is brighter

Accepted Answer

Texture gradient refers to the fact that texture appears to become less detailed in the distance. This is because the elements of a texture appear smaller and less distinct as they get further away, leading to a decrease in perceived level of detail.

Question 10

What are the five primary tastes?&#10;A)hot,sour,spicy,sweet,origami&#10;B)salty,sour,spicy,sweet,tart&#10;C)bitter,salty,sour,sweet,umami&#10;D)peppery,salty,sour,sweet,acidic

Accepted Answer

The five primary tastes are bitter, salty, sour, sweet, and umami. Option A is incorrect because origami is not a taste. Option B is partly correct as it includes salty, sour, spicy, sweet, but tart is not a primary taste. Option D is incorrect as peppery and acidic are not primary tastes.
